Somebody said that they had never heard of David Goyer. Sure you have. He has been the writer behind all of the Blade films, the new Batman, the amazing Dark City and the great Albert Pyun flick - Arcade.
I have a lot of respect for Goyer. Despite Arcade, he has made some amazing flicks, especially Dark City.
As for a clip of Trinity, check out this link:

Looks like a blast of a film. I'm definently there.
